Stop with Core now and just bump up the memory =DThink you can get a bit more from the mem's freq. If you run into trouble bump down the core a little.

Fan speed 50? When playing some heavy graph's try to use atleast 65% or 70% of fan ( I know its noisy but =P )

How much do you think I could get out of the memory and how should I go about testing that? I've been using 3DMark11 and Unigine Heaven to test since Furmark makes the core clock fluctuate for some reason.

I made a custom fan profile and temps never go above 65 C while gaming.
